This patch reverts the patch from https://reviews.llvm.org/D78884 and adds logic to disable comments based on NDEBUG. Original patch removes the indices into the MatcherTable. Controling this via NDEBUG seems reasonable since the debug messages from the SDAG that refer to these are also guarded by that macro (since they are LLVM_DEBUG messages).

Add new cmake option `LLVM_OMIT_DAGISEL_COMMENTS` to control adding of comments in GenDAGISel for none debug builds Ref: https://reviews.llvm.org/D78884
